PRINTING USING COLOR CHANGEABLE MATERIAL |
摘要 |
A printing press for printing data on a substrate, the substrate comprising a color-changeable material. The system comprises a laser diode array comprising a plurality of diodes; a housing to which the laser diode array is mounted, the housing disposing the laser diode array across at least a portion of the substrate; and a processing circuit, wherein the processing circuit is configured to control a parameter of light emitted by each of the plurality of diodes to generate an image comprising a plurality of different colors in the color-changeable material on the substrate, and wherein, for each of the plurality of diodes, the parameter comprises at least one of a wavelength, a frequency, or a power of the light emitted by the diode and the color of a portion of the color-changeable material on which the light is emitted by the diode is determined based at least in part on the parameter of the light. |
